摘要： The invention relates to a stabilizer channel, in particular of a radial compressor or diagonal compressor, having an annular stabilizer chamber which encloses a main flow channel in the intake region of a compressor wheel and is delimited from the main flow channel by an annular bridge. The annular stabilizer chamber is bladeless and is connected to the main flow channel via a downstream inlet channel and an upstream outlet channel. A plurality of flow directing elements are arranged in the downstream inlet channel. The downstream inlet channel is arranged between an upstream part of the annular bridge and a downstream part of the annular bridge. The invention furthermore relates to a compressor, in particular a radial compressor or diagonal compressor, comprising the stabilizer channel according to the invention and to a turbocharger comprising the compressor.

摘要： Disclosed is an outflow region of a compressor. The outflow region comprises a flow channel delimited by a side wall at a shroud side and a side wall at a hub side. The side wall at the hub side has, in a region of the compressor wheel outlet, a contour configured such that, in a flow direction, the cross-sectional areas of the flow channel decrease, pass through a minimum and increase again. In the region of the compressor wheel outlet, the flow channel has a length L which extends from a compressor wheel outlet edge to a diffuser blade inlet edge of a diffuser region. The diffuser region adjoins the region of the compressor wheel outlet and has multiple diffuser blades. Also disclosed is a compressor with the outflow region according to the invention, and to a turbocharger having the compressor.
